Table 2 Spatial resolution limit.
Element | Spatial resolution |
|---|---|
Diffraction grating | w x |
Dispersive fiber | \(|\frac{d{x}_{\omega }(\omega )}{d\omega }|\cdot \sqrt{\frac{4\pi }{|\tfrac{d{t}_{\omega }(\omega )}{d\omega }|}}\) |
Electrical bandwidth | \(|\frac{d{x}_{\omega }(\omega )}{d\omega }|\cdot \frac{{\tau }_{FWHM}}{|\tfrac{d{t}_{\omega }(\omega )}{d\omega }|}\) |
Sampling rate | \(|\frac{d{x}_{\omega }(\omega )}{d\omega }|\cdot \frac{1}{{f}_{dig}\cdot |\tfrac{d{t}_{\omega }(\omega )}{d\omega }|}\) |
